For a long time, the battery life of Apple Watches has been their greatest drawback. The issue was further worsened when Apple introduced an all-in-one sleep-tracking feature with the watchOS in 2020. Instead of increasing the mAh on the hardware, Apple only introduced a feature that notifies users when the battery falls below a certain percentage. Although users were notified when their devices needed a recharge, it failed to resolve the real issue.
The Watch Ultra
In September, Apple launched the Watch Ultra for sale. The Watch Ultra addresses this problem head-on by providing more internal space for the battery. More internal space was created within the watch by including a larger case coupled with slimmer components such as the haptic monitor.
For the rest of the line, Apple is looking for ways to improve its battery life without making substantial changes in hardware. The issue has been addressed through a new Low Power mode that is to be launched with the watchOS 9.
How to turn on the Low Power mode?
On your AppleWatch, go to the Settings section. Scroll down to the Battery option and turn on the Low Power Mode toggle below that. Once the Low Power Mode is turned on, a yellow circle appears on the screen. Moreover, the charging animation and time in Nightstand mode also turn yellow.
When the Low Power mode is turned on, the system disables the always-on display. Background heart rate and blood oxygen measurements, workout reminders and auto workout detection, and certain notifications are also disabled to preserve power.
